-- Monster Battle -- starter.
-- Run with: lua projects/monster-battle/starter.lua

-- TODO 1: build a Monster class with .new(name, hp, attack) and methods
--   :isAlive()  -> hp > 0
--   :hit(other) -> deal math.random(1, self.attack) damage to other,
--                  never below 0, and print what happened.

-- TODO 2: create two monsters (a hero and a goblin) with their own
--         hp and attack values.

-- TODO 3: a while loop: while both are alive, the hero hits, then the
--         goblin hits back if it is still alive. Count the rounds.

-- TODO 4: after the loop, print which monster won.
